The high-speed down link bag inserts (HSDPA) in 3GPP standard family, being defined as the 3G communication protocol to the early stage enhancing of UMTS down link.In HSDPA, utilize the transport channel that is called as high-speed downlink shared channel (HS-DSCH).HS-DSCH is mapped to the physical channel that comprises High-Speed Shared Control Channel (HS-SCCH), High-Speed Dedicated Physical Control Channel (HS-DPCCH) and High-Speed Physical Downlink Shared Channel (HS-PDSCH) here.Though the real data on the HS-PDSCH delivery down link, HS-SCCH is in order to will offer the downlink control channel of UE about the control information of the information on the corresponding HS-PDSCH.HS-DPCCH for will be for example CQI (CQI), encoded control designator (PCI) and/or mix that automatic repeat requests (HARQ) is confirmed or NACK feedback informations such as (ACK/NACK) offers the uplink channel of Node B in advance.In general, feedback information will offer Node B corresponding to the information of the downlink channel status of the downlink channel that is provided by Node B.In this way, Node B can be according to adjusting the emission on the downlink channel corresponding to the feedback information of downlink channel status.
Double small district or double-channel HSDPA (DC-HSDPA) further enhancing to HSDPA for utilizing the carrier wave on the down link to gather.In other words, in DC-HSDPA, Node B can offer UE with two HS-DSCH channels on two carrier frequencies, so that down link is doubled through amount.As specified, DC-HSDPA offers the UE from single sector with two HS-DSCH channels, makes the scheduling of resource that will arrive said UE merge in the said single sector.
When the UE334 (see figure 3) just when the boundary of two adjacent sectors uses the HSDPA service, the amount of passing through of this service is usually owing to inter-sector interference or from the low signal quality of serving sector and limited.Owing to from the interference of adjacent sectors and/or owing to the weak signal from serving sector, the terminal possibly only obtain service under extremely limited data rate.Therefore, in the DC-HSDPA system, when one or two HS-DSCH quality of channel degradation, said sector can be handed over to another sector simply, and it can then offer UE with the double small district.
In one aspect of the invention, illustrated like Fig. 5, maybe be useful be between two or more sectors 514 and 516, have geographical overlapping, make UE510 can be at least in a special period by the service of a plurality of sectors.Therefore, according to radio telecommunications system of the present invention HSDPA service from a plurality of sectors can be provided on single channel.For instance, utilize the setting of two sectors can be called as single-frequency double small district HSDPA (SFDC-HSDPA).Yet, can freely utilize other term.In this way, can benefit from high throughput in the user and the whole system at sector borders place., can different sectors be provided here, maybe can different sectors be provided through different nodes B through same Node B.
Fig. 5 is the concept map of explanation according to the SFDC-HSDPA system of exemplary aspect of the present invention.In the illustrated scheme of Fig. 5, two Node B 502 and 504 provide downlink channel 506 and 508 separately respectively, and wherein said downlink channel is substantially in identical carrier frequency.Certainly, as describing, in another aspect, can provide from the different sectors of same Node B downlink carrier 506 and 508 both.Here, UE510 receiving downlink channel and uplink channel 512 is provided, uplink channel 512 by Node B 502 and 504 both receive.Uplink channel 512 from UE510 can provide (for example) feedback information corresponding to the downlink channel status of corresponding downlink channel 506 and 508.
In one aspect of the invention; Can be at single uplink channel 512 (for example through UE510; HS-DPCCH) go up the feedback information of CQI and PCI etc. for example (comprising each the channel condition information in the said sector) and (for example periodically be transmitted into each Node B; When a Node B is transmitted into said Node B during corresponding in the said sector each; Or when different respective nodes B provide said sector, be transmitted into a plurality of Node B) so that allow the channel status of the downlink channel 506,508 that one or more node B scheduling devices confirm on same carrier frequencies, to be provided by two different sectors.In other words, can receive the uplink signal 512 that comprises from the feedback information of UE with the mode that aspect some, is similar to soft handover through two sectors (for example, at Node B 502 and 504 places).Here, can the feedback information corresponding to different downlink channel be carried out time multiplexing or code multiplexed.For instance, when feedback information being carried out code when multiplexed, can use (for example) to modulate feedback information corresponding to the UE particular channelization code of respective sectors.Therefore, can each feedback signal of (for example, on HS-DPCCH) in up link that receives in the said sector be carried out soft combination, thereby increase the reliability of up link report at the node B receiver place.
When carrying out code corresponding to the feedback information of a plurality of downlink channel 506,508 when multiplexed, can the different channels sign indicating number be used for the feedback corresponding to the related downlink channel of feedback information.Therefore, can on same uplink channel, said feedback be provided for a plurality of downlink channel.Here, of the present invention exemplary aspect in, can the channel code that be used for feedback information be carried out symbols at, so that reduce the interference between the different feedback symbol.In other words, in order to make, can channel code be carried out symbols at utilizing many yards when emission feedback symbol quadrature in fact each other.In others, scrambler possibly differ from one another the step.In other words, the synchronous or aligning between a plurality of channel codes is not that various embodiments are necessary.Yet, the said processing resource of disturbing and being used for receiving feedback information that can reduce synchronously.In this way, can reduce or avoid any indeterminate property of the coupling aspect of the corresponding data bag launched in ACK/NACK report and the down link in the up link.And for the report of the CQI on the up link HS-DPCCH, various aspects of the present invention utilize synchronizing sub-frame.
In another aspect of this invention; In utilizing the sign indicating number book to select to encode said downlink channel each under the situation of the suitable channel sign indicating number that will feed back, can jointly be coded on the single uplink carrier feedback corresponding to a plurality of downlink channel.In other words, can be with the channel code of the single feedback symbol that is selected from yard book with the HARQ ACK/NACK feedback that acts on a plurality of downlink channel of coding.
Another aspect of the present invention is used for the synchronizing sub-frame of the HS-PDSCH on the downlink transmission.Although useful, at the subframe level HS-PDSCH of place channel is not enforceable synchronously.In other words, exist alternative method under the situation of the synchronizing sub-frame that does not have HS-PDSCH, to implement SFDC-HSDPA.Yet, under the situation that does not have synchronizing sub-frame, some problem may appear.For instance, the coupling between the last associating ACK/NACK of HS-DPCCH report and the asynchronous HS-PDSCH TTI possibly need extra process.In addition, owing between the emission of HS-PDSCH and the feedback of the ACK/NACK on the HS-DPCCH than long delay, possibly need more HARQ examples.Further, between the corresponding HS-PDSCH TTI of the last CQI of HS-DPCCH report and two sectors different skews can take place.
In another aspect of this invention, may not on single uplink carrier frequency, feedback information be provided.In other words, although the utilization of single uplink carrier frequency can reduce expense (because it can only need single reflector and antenna), some embodiments a plurality of uplink carrier frequencies capable of using.For instance, once more referring to Fig. 4, in an example, UE450 can comprise an above reflector 456, frame emission processor 482 and/or emission processor 480, and an above antenna 452.In an example, then, the UE that receives SFDC-HSDPA can provide the feedback to two downlink channel 506 and 508 on two different uplink carrier frequencies.In other words, one in the said uplink carrier frequency can be corresponding to providing one of downlink transmission in the said sector, and second uplink carrier frequency can be corresponding to second sector that downlink transmission is provided., lack the motivation of any scrambler that is used for corresponding feedback symbol being carried out symbols at here, because said symbol is launched and quadrature on different carrier frequencies owing to it.Those skilled in the art will realize that; Only provide this correspondence one by one here, and have many other suitable embodiments, for example as an instance; In the said uplink channel each different time corresponding to said downlink transmission both, or the like.
Aspect of the control channel signaling that is used for the SFDC-HSDPA system, from each sector of downlink channel is provided, UE can be on one or more HS-SCCH of every sector receiving scheduling information (when UE obtains dispatching).In another aspect of this invention, can utilize one or more HS-SCCH on the sector of host sectors being regarded as, to provide corresponding to control information through data dispatching from two sectors.
And, with respect to HS-PDSCH emission, the frame between the sector capable of using synchronously.In this way; When on two sectors, dispatching UE simultaneously; Can use interference eliminated (also being called as inter-cell interference cancellation) between the HS-PDSCH that the those skilled in the art knows, pass through to measure thereby further improve to these sector borders user's pass through amount and whole system.The those skilled in the art will be familiar with the notion of interference eliminated between HS-PDSCH, and interference eliminated can be in order to reduce the interference from adjacent sectors between HS-PDSCH.In other words, because nonopiate, so when the signal listened to from another sector, can seem to be similar to noise from the signal of a sector from the emission (it utilizes different spreading codes usually) of different sectors.Yet said signal in fact is not only a noise, and for example receiver such as UE can have the information about said signal, for example, and the spreading code that is just utilizing, or the like.Therefore, interference eliminated reduces the interference from another sector between receiver HS-PDSCH capable of using.In addition, UE can confirm the gained feedback relevant with channel status (for example, CQI) time consideration from the improvement of inter-sector interference elimination.In other words, the channel quality that is reflected among the CQI on being provided in uplink transmit is decided by interference eliminated between HS-PDSCH.
Therefore, can define main sector and minor sectors by dynamical fashion.In other words, though the feedback information on the corresponding HS-DPCCH of main sector can make maybe noiseless elimination (for example) when only on single sector during scheduling UE, this feedback also is accurately.Certainly, the feedback information corresponding to minor sectors can be accurately when in fact on two sectors, dispatching UE only.In addition, the further optimization of control channel signaling can make and can under the situation that conventional linear receiver is worsened, use interference cancellation techniques efficiently.
Those skilled in the art will appreciate that some aspect of SFDC-HSDPA can be similar to soft handover.In other words, the user is the receiving downlink information from biparting district in fact simultaneously, thus increase through amount and reliability both, simultaneously the specific uplink emission is offered each in the said biparting district.Therefore, for instance, when the boundary of user, can reduce or avoid the bad performance of the expection that (for example) caused by inter-sector interference two sectors.In other words, if the user is served by first sector, and if the improvement of second sector, can change serving sector so, make and can come service-user through more suitable sector.For instance, the specific geographical location that overlaps each other or contact in the zone corresponding to two sectors possibly be difficult to confirm that which sector is preferred, and in addition, the preferable appointment in which sector can change along with the time at boundary apace.What therefore, come in handy is to send simultaneously from two sectors of data.In this way, can be at the borderline region place service-user better.
